Headstamp ID Needed

I have some expended Brass, 30-06 marked PB 74 or maybe P8 74 & has no visable Primer Crimp. I believe it to be South Korean Surplus. From what I know some of this is corrosive & some isn't.

South Korean is Corrosive without a doubt.

Marked, " PS or P8 over 73" Korean? Corrosive? 2 found their way in the mix at the Range Sunday. Someone was firing it and some how was thrown in my pile. I done tumbled and resized them before I picked up on it. If corrovsive will this contaminate the rest from the Tumbler?

I found this in my notes, can anyone confirm this to be true?

It's "PS 74", and it is indeed Korean. It is noncorrosive. The corrosive Korean ammo is marked "KA".

No, but those two cases are toast, chuck 'em.

PS is good to go, KA is corrosive and once fired and cleaned is good reloading brass.
